How to install docker on
PFC100
Not officially supported! Use at your own risk.
Please use PFC200 G2 with Docker in production.

The PFC100 only has 256MB of eMMC flash memory internally, of which only 32.6MB is available in root partition. !
This is not enough storage for docker + containers.!
The work around is to prepare a special SD card to boot and run docker, which this procedure explains.!
This requires many steps, and is not ideal.!
This is not recommended for production use, only testing as SD cards are not as reliable as eMMC.
Question: Why can’t I install docker on the PFC100? Why does it fail when I try to install it?

Step 1:
Download FW17 from this location!
https://github.com/WAGO/pfc-firmware/releases
Step 2:
- Download Balena Etcher from this location!
https://www.balena.io/etcher/!
- Install the application
Step 3:
- Insert a blank SD Card (8GB or 16GB) into USB SD Card Reader!
- Plug this into your computer
Step 4:
Use Balena to create a bootable FW17 image on the SD Card.
Step 5:
- Insert this SD card into the PFC100. !
- Apply 24VDC power
Blank

Step 6:
Use Ethernet Settings find the PFC100 IP address if you have a DHCP server.!
If not, you can use the ‘RST button trick’ (See below) optionally.
‘RST button trick’
Put PLC in stop Press RST for 7 seconds SYS light blinks orange Static IP: 192.168.1.17/24
DHCP
Note: this is temporary, a
reboot will go back to the
firmware IP settings
(DHCP, Static IP, etc.)

-Turn offPLC!
-Remove SD Card!
-Apply 24VDC to power PLC
Step 7: Step 8:
-Connect to the web based management using IP from step 6.!
- Log in with admin / wago)!
- Verify FW17 on Information>Status page.
Step 9:
Blank
- Insert a blank high quality 8GB or 16GB SD Card into PFC100
- Navigate to Configuration>Administration>Create Image!
-Click [Start Copy] Button to prepare the internal flash with FW17.!
-Wait until copy is complete (~2 min)
Wait about 2 minutes for boot up
FW17

- Connect to the web based management using IP from step 6.!
(Log in with admin / wago)!
-Navigate to Configuration>Administration>Create Image!
-Select menu option “Full Card Size”!
-Click [Start Copy] Button to prepare the internal flash with FW17.!
-Wait until copy is complete (~3-5 min).
Step 10:

Do not remove SD Card from this point on! Consider putting tape over SD Card bay door to prevent
accidental removal.

-Power cycle the PFC100!
-Verify the PFC is running from SD Card. !
-You should see yellow activity light on SD card during boot process.
Step 11:
Step 12:
-Now you have the full 8GB (or 16GB) of flash memory for docker to use.
Before (stock) After (Boot from SD Card)
32.6MB Available 6.7GB Available

Step 13:
-Navigate to Configuration>Software Uploads
Step 14:
-Download the docker ipk file. This can be found here:!
https://github.com/WAGO/docker-ipk/releases
-Download the file: !
docker_19.03.13_armhf.ipk
Click choose file
Find file from step 13, click [Open] button
Click [Install] button
Wait about 2 minutes. Click [OK] button.

Docker is installed!
Step 15:
-If using DHCP, proceed to step 18.!
-If using Static IP, set network DNS to 8.8.8.8 !
Step 16:
-Verify PLC can ping google with ssh.!
If not using macOS, Linux or Win10, then you can use putty for ssh.
Step 18:
-If using DHCP, proceed to step 18.!
-If using Static IP, enable and set gateway address.!
Typically this is xxx.xxx.xxx.1 !
Step 17:
Click [Add]
Click [Submit]

-Set time zone
Step 19:
-Set time server & press [Submit] button
Step 18:
-Press [Update Time] button, and verify correct time with PC
-Verify you can pull an image
Step 20:
-Verify image completes.
